Samsung unveils 4-Gb LPDDR3 mobile DRAM

A 4-Gb LPDDR3 DRAM for mobile devices offers speed and data capacity comparable to DRAM used in PCs. Utilizing 20-nm-class process technology, the memory from Samsung transmits data at up to 2,133 Mb/s per pin. This rate allows a smartphone or tablet to transmit 17 GB of data (the equivalent of three full high-definition videos) in 1s.

The device generates more than a 30% improvement in performance and 20% savings in power consumption over 30-nm-class LPDDR3 DRAM. The module also allows mobile device OEMs to offer a 2-GB package that includes four of Samsung's new chips in a single package of 0.8-mm high.

Samsung plans to increase production of its 20-nm-class mobile DRAM later this year. Click here for more information.
